I too am experiencing the freezing of the UI occasionaly when certain windows open. The first time it happened was on a nautilus "properties" dialogue window. It seems it isn't limited to popup windows though as I've gotten the hang while opening programs too. I've only had to kill X once, the other times I just waited a bit and it resolved itself.
